Can we retain ticket number for corporate card transactions

Summary:

for AMEX transactions, we have enable ticket number for airfare expenses. When the data is pulled to Oracle, the description field, merchant name field and ticket number is getting auto populated from AMEX statements.

The expense type mapped under corporate card mapping is Airfare domestic. All these above fields are auto populating with expense type as airfare-domestic from AMEX statements. When the user wanted to change the expense type from Airfare domestic to Airfare international, the user goes to each card expense item and changing the type to Airfare international. While changing, the ticket number value is not retaining. It is becoming blank.
